Great company to work with Ordered a couple Charge pipes due to Ford being on national back order and Sinister Diesel was able to help out with having theirs available. Great quality products, friendly service and quick responses.

Great quality products at clove itompetitive… Great quality products at competitive prices

customer service/ parts Not the greatest customer service. Had to call twice for order issues. First time I called they were rude second time I called was better. Parts I ordered had no real change in performance. More for just color and look under the hood.

Quality Parts, Fast & Free Shipping We have ordered from Sinister Diesel before and I know it is a website we can trust to order from, and the parts arrive in just a couple of days. If we have any questions, it is easy to reach a person in customer service and they are knowledgeable about the products we are purchasing and are able to answer any questions we have. Maybe there are cheaper parts available on the web, but you get what you pay for and these parts are quality! Thank you!

Easy to find the part Easy to find the part, really should not have went out in the first place. But glad they had it. It was the on an off valve for the water filter. Was leaking. Poor construction is all I can think, plastic ball valve. Got 3 years out the older one. The price you pay for this stuff should be made unbeatable.
